SEPARATOR FOR GAS AND WATER.

SPECIFICATION forming part of Letters Patent No. 761,109, dated May 31, 1904.

Application filed October 17, 1899.

To all 'w/wm/ it may concern:

Be it known that I, ALoNzo J. SIMMONS, a citizen'of the United States, residing at 3211 Kemwood avenue, Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Separators; and I do declare the following to be a full, clear, and exact description .of the invention, such as will enable (others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form apart of this specification.

This invention relates to separators in general, and more particularly to that class employed in the separation of gas from water in combination with which it usually flows from the gas-well.

The object of the invention is to provide a operation, the water-outlet from the separator being regulated by the column of water within the stand-pipe.

Afurther object of the invention is to pro- Vide an automatic relief-valve in which the parts will not be subject to the corroding efspecifications.

.In the drawings forming a portion of this specifiation, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the com plete apparatus. Fig. 2 is a vertical central section of Fig. '1. "Fig. 3 is a bottom plan view of Fig. 1.

Referring now to the drawings, this separator comprises a stand-pipe or receiver 5, which is preferably cylindrical in form and is of sufiicient height and diameter to insure the separation of the gas from the water in the descent of the mixture therethrough. To the lower end of the stand-pipe is secured a base Serial in. 733,890. (No model.)

forms the base for the automatic relief-valve.

This base 6' is securedto the lower. end of the stand-pipe'through the medium of a ring-8, which is screwed onto the lower end of the stand-pipe 'andto which ring the base is secured by means of bolts 9, as shown.

Upon the-upper end of the stand-pipe 5 is screwed a cap 10, having a transverse hori- Zontal partition 11, which rests upon the upper end of the pipe. Above this partition the cap is contracted transversely, as shown in Fig. 1 of thedrawings, and this'contracted portion is divided into two chambers by a vertical partition12, these chambers being designated 18and 14L in the drawings and having openings 15 and '16 in their bottoms through the partition 11 and into the inclosu re of the stand-pipe. Screwed into the opening 16 is a nipple 17 which depends vertically and stand-pipe, this mixture being supplied di-' rectly from the well through a feed-pipe 18, leading from the 'well to said chamber. A gas outlet pipe, 19 communicates with the chamber 13 through a side wall thereof, as shown.

Mounted upon the extension 7 of the base 6 is a cylindrical valve-casing 20, having outwardly-directed flanges 21 and 22 at its upper and lower edges, respectively. This shell is disposed upon the extension 7 and has a head 23 at its upper end and resting on the flange 21. The shell, the head, and the base extensions are held in their proper positions by means of the bolts 24, passed through alining perforations formed in the flanges 21 and 22, the head 23, and the extension 7.

Upon the base 7 and between it and the shell 20 is disposed a disk of rubber 25, and

within the shell 20 and resting upon this disk is a piston-valve26, which "is in the form of a cylinder having an open upper end and a reentrant lower closed end, the disk being held extension 27, which is secured over the rubber disk and to the central portionof thebase of the piston-valve, as shown in Fig. 2 'of the drawings.

In the inner periphery of the shell is formed a broad channel which is covered by the piston valve 26, and in this resultant chamber is disposed a packing 28, formed, preferably, in accordance with the invention set forth in United States Letters Patent No. 120,003, granted to me.

Centrally of the base extension 7 is formed a recess 29, which communicates with a passage 30, which leads radially and outwardly of the said base extension and communicates with a drain-pipe 31, which has threaded connection with its outer end. The valve pad or extension 27 acts to normally close or cover the recess 29 to prevent egress from the standpipe 5 by way of the passage 32, which leads from the center of the bottom of the standpipe to a point through the bottom of the base extension 7 midway between the center of the valve-casingand the periphery thereof. When, however, the valve pad or extension 27 is raised from the recess 29, there will be a flow of liquid through the passage 30.

An equalizing-pipe communicates at one end through the top of chamber 13 and at its other end through the head 23, so that the pressure within the stand-pipe may be conveyed to the upper side of the piston-valve 26 to balance the pressure from the standpipeupon the lower end of the piston-valve.

The operation of the structure is as follows: Fluids in the form of liquids and gases in a mixed state enter the chamber 14 through the pipe 18, and from said chamber they pass downwardly and through the nipple or nozzle 17. After dripping from the nozzle the gases, due to their buoyancy, separate from the fluids, and while the liquids accumulate in the stand-pipe the gases pass upwardly through the opening 15 into the chamber 13 and thence through the supply-pipe 19 to the main. The gas in the stand-pipe has of course a specific pressure, and this pressure is communicated to both sides of the piston-valve 26, so that the latter remains stationary and holds its extension 27 over the recess 29 and prevents and passage 30 and will be drained off. There is always a certain quantity of liquid within the stand-pipe, and which water has a sufficient hydrostatic pressure to balance the piston-valve, or rather slightly less than that amount, whereby as soon as the liquid in the stand-pipe is drained sufficiently to reach this point, the drainage ceases, due to the closing of the recess 29, and begins again as soon as the liquid has reached the proper height. It will furthermore be seen that with this construction while the rubber disk 25 permits the operation of the piston-valve it precludes the access of the acidulated fluids to the work- Having thus described my invention, what 7 I claim is 1. In a separator comprising a base having a stand-pipe mounted thereon, a cylindrical valve-casing mounted upon the base, a passage through the base connecting the standpipe with the valve-casing, a second passage through the'base leading to the valve-casing, a diaphragm-clamp between the casing and base and carrying a valve adapted to normally close the second passage through the base, a cylindrical piston in the casing and having a lower reentrant head attached to the diaphragm and valve, and a pipe connectingthe casing above the piston with the. stand-pipe.

2. A separator comprising a receiver, a cap for the receiver inclosing a separate gas-receiver, and gas-outlet chambers, a gas-outlet pipe connected with the inlet-chamber, a gasoutlet pipe connected with the outlet-chamber, a pipe leading from the inlet-chamber into the receiver below the cap, a drain-passage in the receiver, a valve for the drainpassage adapted to be opened by pressure from" the receiver, and a cylindrical pipe leading from the valve to the outlet-chamber.

3. A separator comprising a receiver, a cap for the receiver inclosing aseparate'gas-inlet chamber and gas-outlet chamber, a gas-inlet pipe connected with the inlet-chamber, agasoutlet pipe connected with the outlet-chamber, a pipe leading from the inlet-chamber into the receiver below the cap, a. drain-passage in the receiver, a valve adapted to close said passage, said valve being raised and lowered by the pressure within the receiver, and an equalizing means in communication with the valve andthe outlet-chamber.

In testimony whereof I affix my signature in presence of two witnesses.
